Sugars as Energy Storage Molecules01:10

Sugars as Energy Storage Molecules

9.2K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...

Carbohydrates: Dietary Sources and Requirements

1.0K
Carbohydrates are predominantly obtained from plant sources. With the exception of lactose found in milk and insignificant glycogen amounts in meat, most consumed carbohydrates have plant origins. Monosaccharides and disaccharides, or sugars, can be sourced from fruits, honey, milk, sugar cane, and sugar beets. Grains and vegetables are rich in the polysaccharide starch. Two types of polysaccharides provide fiber: cellulose, which is abundant in many vegetables, forms undigestible roughage or...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

12.9K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Glucose Transporters01:27

Glucose Transporters

26.4K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Overview of Carbohydrate Metabolism01:19

Overview of Carbohydrate Metabolism

2.4K
Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.
Glucose transport into cells is facilitated by a family of transport proteins called GLUT (Glucose Transporters). GLUT4 is the primary glucose transporter for insulin-stimulated glucose...

Glucose Absorption Into the Small Intestine01:26

Glucose Absorption Into the Small Intestine

33.6K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

Area of Science:

  • Nutrition Science
  • Public Health
  • Dietary Assessment

Background:

  • Free sugars (FS) are linked to significant health issues, including dental caries, weight gain, obesity, and type 2 diabetes.
  • Canada's Food Guide advises limiting free sugars to mitigate these health risks.
  • Accurate estimation of free sugars intake is essential for developing effective public health policies and interventions.

Purpose of the Study:

  • To estimate the free sugars intake among Canadians aged one year and older.
  • To introduce and apply a novel method for quantifying free sugars content in foods within the Canadian Nutrient File.
  • To identify major dietary sources contributing to free sugars consumption in the Canadian population.

Main Methods:

  • Utilized a newly developed method to estimate the free sugars content of foods listed in the Canadian Nutrient File.
  • Analyzed dietary data from national nutrition surveys to determine free sugars intake.
  • Defined free sugars as sugars whose structures have been altered during food processing.

Main Results:

  • Free sugars constitute approximately 12% of total energy intake (around 56g per day) for Canadians aged one year and older.
  • The primary sources of free sugars were identified as sugars/syrups/preserves/confectionery/desserts, soft drinks, baked goods, and juices (without added sugars).
  • These top four sources collectively accounted for 60% of the total free sugars consumed by the population.

Conclusions:

  • Sustained public health efforts are necessary to reduce free sugars consumption across Canada.
  • Particular attention should be directed towards children and adolescents, who are at high risk due to their dietary habits.
  • The findings underscore the importance of monitoring and reducing free sugars intake to improve population health outcomes.
